Ballsy spammers

If you have to force a site to delete your own spam, you're doing it wrong.

Comment spam is the bane of one's life on the internet; there's probably some underneath this very post (if there isn't, there will be). Spammers post little messages with little relation to the content above, and link to their, generally scammy, site.

The intention isn't really to trick individuals to click on the post, because even spammers know that people don't tend to be that intrigued. Instead, it's to game Google Search rankings, which are determined by the number of sites which link back to yours.

For quite some time now, Google has deliberately ignored links in comments, knowing that they have nothing to do with the owner of the site. That hasn't stopped the spammers, of course, who aren't known for making sense, but it has at least dampened their effects. But recently, it went one step further, and started actively penalising sites which engage in spam.

All of which led to the American politics site, TPM, receiving a cease-and-desist letter from a spammer, asking them to delete previous spam from their site. Josh Marshall, the editor, writes:

In other words, the estimable businessmen and women at have been paying SEO companies to spam the comment sections of sites around the globe. But now Google’s new search algorithms are making that legacy spam really damaging. So now they’re sending out cease and desist notices to the victims of their earlier spamming demanding that they search their archives and remove their spam.

Why have men become so lonely – and how does it affect their health?

New findings show the consequences of having a lonely heart.

Go out and get some friends. No, seriously. Hop on the Tube and act faux-interested in the crap-looking book your fellow commuter is reading, even if it's on their Kindle. Chances are it's better than the one in your bag, and they're probably a decent human being and just as lonely, like you and me.

A new slate of facts and figures are showing just how widespread loneliness, is while simultaneously being amazingly terrible for your health.

Research led by Steven Cole from the medicine department at University of California, Los Angeles is showing the cellular mechanisms behind the long known pitfalls of loneliness. Perceived social isolation (PSI) – the scientific term for loneliness –increases the exposure to chronic diseases and even mortality for individuals across the world.

The authors examined the effects of loneliness on leukocytes, also known as white blood cells, which are produced from stem cells in the bone marrow and are critical to the immune system and defending the body against bacteria and viruses. The results showed loneliness increases signalling in the sympathetic nervous system, which is responsible for controlling our fight-or-flight responses, and also affects the production of white blood cells.

Recently, the Movember Foundation, which focuses on men's health and wellbeing, carried out a survey with the help of YouGov investigating friendship and loneliness amongst men. The results are alarming, with only 11 per cent of single men across the spectrum in their early 20s to late-middle age saying they had a friend to turn to in a time of crisis, the number rising to 15 per cent for married men.

Friendship has shown not only to be important to a person's overall wellbeing, but can even add to a person's earnings. A previous study involving 10,000 US citizens over 35 years showed people earned 2 per cent more for each friend they had.

The Movember Foundation survey comes soon after the Office for National Statistics (ONS) showed that men in Britain make up 58 per cent of the 2.47m people living alone between the ages of 45 and 64. The reasons behind this figure include marrying later in life and failed marriages, which usually result in children living with the mother. Women still make up the majority of the 7.7m single-occupant households across all ages in the country, at approximately 54 per cent.

Chronic loneliness seems to have slowly become a persistent problem for the country despite our hyper-connected world. It's an issue that has made even Jeremy Hunt say sensible things, such as "the busy, atomised lives we increasingly lead mean that too often we have become so distant from blood relatives" about this hidden crisis. He's previously called for British families to adopt the approach of many Asian families of having grandparents live under the same roof as children and grandchildren, and view care homes as a last, not first, option.

The number of single-person households has continued to increase over the years. While studies such as this add to the list of reasons why being alone is terrible for you, researchers are stumped as to how we can tackle this major social issue. Here's my suggestion: turn off whatever screen you're reading this from and strike up a conversation with someone who looks approachable. They could end up becoming your new best friend.
